RE: Hi (Exercising and Losing Weight)

[Guest guest]

Hello ,

The word " calories " is central to Calorie Restriction,

but doesn't appear in your message.

Exercise sounds commendable. Lowering weight sounds commendable.

And getting exercise and lowering body weight -- both of those

sound doubly commendable. But if you leave the calories you consume

unchanged or even increased (if you exercise a lot), you have

gained nothing (and possibly even lost something) by the laboratory

CR yardstick of reducing calorie intake.

That sounds horrible, because you have tried to do a double good

but gained no CR benefit at all (or actually lost something),

per laboratory test results that uniformly point to this rather

ugly truth -- CR is about reducing calories, and it is only

by the reduction of calories whereby CR benefits are obtained.

Subject: [ ] Hi

Hello to all.

I'm new to CR - started in February of this year after seeing Dr.

Walford on a repeat episode of <I>Scientific American Frontiers<I>.

I've combined moderate strength training and aerobics most of my

adult life (I'm 42). I've eaten what would be considered a " healthy

diet " by most standards since early adulthood. My blood pressure and

cholesterol levels have always been excellent. BP usually around

115/65 and my total cholesterol was 149 nonfasting pre CR. I'm 6'2 "

and my weight was usually around 180 to 185 pounds

I stopped working out about a year ago during a stressful period of

my life (post divorce issues) and gained 20 pounds before buying a

treadmill late last fall. I lost about 8 pounds in December and

January and from February to present, I lost 32 pounds on a moderate

CR diet. I now weigh 168 lbs.

When I started CR I started to train twice a week with weights again

along with thrice weekly 25 minute treadmill workouts. According to

the measurements I've taken, I've gained muscle in my upper body and

lost a lot of fat in the abdominal region. The difference in a few

short months is astonishing. I can actually see my abdominal

muscles.

My goal weight is 160 lbs. I'll take stock of my progress when I

reach this weight. I'm not keen on losing muscle mass and am focused

more on fat loss and hope to maintain about a BFP of around 6-8%.

I welcome any comments or suggestions.

Hi Warren,

The weight I have lost so far has been a result of a combination of

dietary caloric restriction and a caloric deficit resulting from

moderate exercise. I don't burn more than 2500 calories a week with

exercise so I doubt I've decreased my longevity. Walford explains on

p. 203 in BT120YD that exercising CR mice live just as long as

sedentary CR mice.

As I pointed out in my introductory post, I lost 32 pounds in about

18 weeks on a moderate CR diet. I primarily followed the the menus

in BT120YD but ate slightly bigger portions with snacks between

meals. While 168 might seem high to some, I am 6'2 " . This gives me a

BMI of 21.6. This would put me in the lean category with lean being

a BMI of less than 23.

My goal is primarily to strip away fat and not lose too much lean

body tissue. The only way to prevent the loss of lean body mass

while losing weight is to train with weights. The modest aerobic

workouts will add to the weekly caloric deficit. Being able to

maintain a low percentage of body fat through caloric restriction

should yield a modest CR benefit.
